Is the 2016 500X getting worse?

Pass rate of 2016-registered cars across recent test years:

Test year	Pass rate
2023	81.2% -1.9 vs same-age
2024	76.6% -4.6 vs same-age
2025	72.6% -7.0 vs same-age

The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

FAQs

Is a 2016 Fiat 500X reliable?

2016-registered examples passed 76.8% of their MOT tests (40,690 tests, 2023–2025), -4.5 points versus all UK cars registered in the same year. At roughly 10 years old with a median 55,383 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2016 500X?

The median tested example shows 55,383 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.

Should I buy the petrol or diesel 2016 500X?

In this cohort petrols pass 78.7% of tests against 74.4% for diesels. Mileage and use can explain part of that gap, so treat it as a reason to inspect DPF and emissions history, not a fuel-type verdict.
